Meet BJF partner and friend: Mijn Steen!

By Invisible on news page

Are you in need of a new office or home in Amsterdam, Utrecht, or Zwolle?

Jetze Steensma is expert in real estate, which includes selling and leasing back Offices, investing in and developing offices, and creating building plans that are good for you and the Earth. Jetze sees sustainability as one with real estate. His policy is to connect every project with the question – is this sustainable or not? If not, he can’t stand behind it!

As Jetze puts it:

“Contributing to Sustainable and Circular building development is what makes our heart tick“

By focusing on sustainable projects that are both price competitive and circular, Jetze’s company, Mijn Steen, is shaping the world of real estate.

How is Mijn Steen shaping real estate?

The Real Estate market is focussing increasingly on wood and stone. As real estate consultant and developer, Mijn Steen has often been asked to assess the possibilities of wood and stone as sustainable building components. After speaking about this with various experts in the field, they came to the conclusion that both materials can be used responsibly.

The advantage of wood is that wood exists as a result of photosynthesis; converting carbon dioxide into oxygen and (growth) sugars. This is one of the oldest and most sustainable processes of our world. is a specialist in sustainable development and is committed to sustainable housing. Our motto for timber construction is to provide a solid replanting program to protect forests, forestry and landowners.

Partnership with the Black Jaguar Foundation

Besides ensuring more sustainable design of the buildings they develop, Mijn Steen also supports the Black Jaguar Foundation in realizing the Araguaia Biodiversity Corridor!

The Black Jaguar Foundation is very grateful to have Mijn Steen as a sponsor partner and BJF friend. A few years ago, we were in need of a new office and Jetze very kindly procured a location which is now partially sponsored by Scalehub! Have a look at our lovely office space below:

Our new office even has a special Black Jaguar Foundation promotional stand at its entrance – so that anyone entering the building can immediately get to know us!

Giving Tuesday is here; a great opportunity to support a cause you, our planet and our future generations need.

It  motivates us to see so many organizations and individuals united to promote a culture of giving in Brazil and around the world. The Black Jaguar Foundation is happy to join this movement, and you are all invited to join us.

The 22/23 planting season has started!

By Invisible on news page, News Home

Our field teams are in full preparation mode, preparing the soil and putting this planting season’s first seedlings in the ground!  

As always, the team has been incredible this year, adapting and creating solutions to plant as many native trees as possible despite the challenges we have faced. 

During the last planting season, we observed incredibly positive results when planting via direct seeding. For this reason, we have decided to use direct seeding as a restoration method for around half of our restoration areas.  

What is direct seeding?

Direct seeding refers to planting native seeds directly in the area to be restored. Have a look at how this technique looks below:  

Our team usually grows during the planting season, so that we can plant as many native trees as possible. This makes safety measures especially important during this time. To ensure the well-being of the team, our dedicated work safety engineer, Matheus Monteiro dos Santos, has been working hard to develop health and safety measures and ensure that these are in place at all of our restoration sites and nurseries. 

Health and safety procedures

Before our team starts carrying our ecological restoration, they go through different medical exams, as well as practical and theory training sessions in work safety, and safe operation of machinery.  

Have a look at some of the BJF team after their first theoretical and practical training sessions:

Have a look at the incredible growth of our trees!

Two years ago, we planted many native trees, of only 30 cm in height. Now, many of these trees have grown to over four meters high!

We have also been finding regenerating species that were not planted by us, which is one of the best signs that our ecological restoration efforts are working. 

Watch our forest engineer Dimitrio Schievenin explain the wonderful growth of our trees:

Walk through this 1.5 year old restoration site with our community outreach coordinator Joël Boele!

What else do healthy forests have? Seeds!! We are happy to share that many seeds  have also been growing on our trees. 

Have a look at the seeds growing on our trees!

None of this would have been possible without all of the support we receive from our wonderful sponsor partners. Thank you for your commitment to realising the Araguaia Biodiversity Corridor.  Below, please see a video message from our initiator Ben Valks, straight from the field!

These healthy and resilient trees, growing at the heart of the Araguaia Biodiversity Corridor, are only the start. It motivates us to see how far our restoration efforts have come, and we look forward to planting many more trees!
